Hello Everyone,I have dealing with STM32F407 I2C peripheral in order to implement Non-blocking communication.I have made many trials but I2C1 event and error interrupts never occur. I checked the SB bits during the debug mode it becomes 1,the other r...
I've turned on VREFBUFF. Datasheet claims that factory trim values should be automaticaly loaded into VREFBUF->CCR. Thru debug i can see that CCR=00000 (no relevant value loaded). And measurments at VREF+ confirm that.REF 2.5 = 2.431VREF 2.048 = 1.99...
I've been developing my own I2C interface. When the BTF is set, I issue STOP. However, the interrupt routine is repeatedly called until the STOP is generated..In document it says that BTF is cleared by hardware after a start or stop condition in tran...
Sorry guys i am just starting with MCUs generally , i am now playing with NUCLEO boards , ran a couple of programs like LED , External interrupt . But came across the expansion board and in the datasheet they have given it uses DFSDM , but i cannot...
What I would like to do is the following:1) Take a pair of the STM32F103C8T6's 16-bit timers and link them into a 32-bit timer (I'm pretty sure there's an app note somewhere that describes this)2) Then, configure that 32-bit timer for input capture (...
Posted on June 12, 2018 at 03:45On a project that used to generate code just fine for months, STM32CubeMX now gets stuck. This is happening since an upgrade to version 4.26.0. If it is of any relevance, the project uses the STM32L4 package version 1...

Dear experts, I'd be grateful if you could point me to some basic CAN bus example code for the F103 (blue pill) which later may be ported to the F4xx family (most likely F423)Thanks for your help!
hello!Recently, I found such a problem: when the MCU works at 32MHz by default, it can enter the low power mode normally. However, in order to reduce the power consumption during operation, when I reduce the system frequency below 4MHz, the MCU can't...
